please help, doggy won't poop

Sorry I can't type Chinese here.  My schnoodle girl hasn't pooped 3 days. I found my terri-poo boy wiping his bottom on the lawn, seemingly trying to poop but only a little bit came out.   They ate a huge steamed bun, which is not their usual diet : (   The vet  won't be able to see them until tomorrow evening.   Anything I can do to help them now?  Also, can I do anything to prevent this in the future?   Any suggestion would help. Thanks~

• 那應該問題不大。有時狗狗運動不夠或吃了熟的骨頭會大便幹，便秘啦。吃點菜 -yiyi777- ♀ (0 bytes) () 02/24/2015 postreply 12:33:04

• 如果腸胃被堵住了是很危險的，現在吃什麽喝什麽都不重要，趕緊去看醫生，如必要做一個X-ray確診腸道是通的。 -corgi- ♀ (0 bytes) () 02/24/2015 postreply 20:11:29
